It's hard to believe it's been five years since we first heard about Maria Kang, the fitness model who was accused of "mom-shaming" other parents on social media.

Kang made headlines after sharing a photo of herself flaunting her abs next to her three sons on social media. What drew controversy was Kang's question "What's your excuse?" written above the picture.

Other parents accused Kang of shaming them with unattainable and unhealthy beauty standards, but the mother-of-three refused to back down.

Even when she offered an "apology" for the photo, it struck many as less than sincere.

“What you interpret is not MY fault," Kang wrote. "It’s Yours. The first step in owning your life, your body and your destiny is to OWN the thoughts that come out of your own head. I didn’t create them. You created them. So, if you want to continue ‘hating’ this image, get used to hating many other things for the rest of your life.”

Kang doubled down on her critics, arguing she was being "fit shamed" for her healthy lifestyle.

Now, five years after igniting a national debate, Kang is making waves again with an update to her original photo.
